The Lever component describes a mechanical actuation of a valve. This model is based on the PreLoad example (located in MapleSim under the Libraries tab in the ExamplesPhysical Domains1-D Mechanical palette).

When designing hydraulic valves, it is often necessary to hold the spool in a certain position as long as an external force is below a threshold value. If this force exceeds the threshold value, a linear relation between the force and the position is desired.

There are designs that need only one spring to accomplish this task. Using the ElastoGap component this design can be easily modeled.
